PROCESS OF STORING ACETYL ENE GAS.

SPECIFICATION formingpart of Letters Patent No. 662,258, dated November 20, 1900.

Application filed April 8, 1897. Serial No- 631,319. (No specimens.)

16 gas has at normal temperatures a pressure in excess of six hundred pounds to the square inch. It is also known that highly-compressed acetylene gas under some circumstances can be suddenly decomposed. Acetylene gas is' when liquefied in the most condensed form now known, but the pressure is considerable, and for some purposes it would be important to diminish this pressure, at the same time avoiding any risks of a violent de- 20 composition being carried through the mass.

I have discovered that liquefied acetylene gas can be mingled with other liquids-as, for instance, fusel-oilin such proportions that it becomes practically part of the fuseloil and is absorbed by or combined with it.

This operation likewise reduces the pressure of the liquefied acetylene to a great extent, dependent upon the proportion of liquefied acetylene which may be mingled with or absorbed by the liquid absorbent.

By my process I propose, in the first place, to liquefy acetylene gas according to the process now well known. It can then be transported, if desired, to the place of use. If

5 then it is mingled with a liquid, such as fuseloil, in suitable proportions, the pressure of the acetylene will be greatly diminished, and the acetylene, being mingled with the fuseloil, will prevent an explosion passing through Several times the volume of gaseous acetylene can thus be mingled with the absorbent and disappear therein, and this gas will be given off as the pressure is again reduced.

I do not claim to be the first to discover that acetylene can be absorbed by liquids, my invention being limited to the preliminaryliquefaction of the acetylene and its subsequent mingling with the absorbent. I do not limit myself to fusel-oil, as other liquids may be employed. Absolutealcoholisagoodsolvent, though volatile. Acetone is also a solvent.

The amount of acetylene to be added to the solvent will be readily determined by the fact that if no more is added than the solvent will dissolve the pressure willbe reduced several hundred pounds below that of the liquefied gas. Of course if too much liquefied gas is added the pressure will increase to that of the normal pressure of such liquefied gas. t

In practice I provide a cylinder containing a known amount of the solvent. To this I connect the cylinder containing liquefied gas through an intermediate chamber having proper capacity and having stop-cocks above and below. The connection being made, I allow the liquefied gas to pass into the intermediate chamber by openingthe upper stopcock. Then closing this and opening the lower stop-cock the liquefied gas passes into the body with which it is m'scible. Then closing the lower stop-cock an the stop-cock upon the receiving-chamber tyle operation is completed.

What I claim as my invention, and desire to secure by Letters Patent, is

The process of preventing explosions and reducing the pressure of acetylene gas, which consists in mingling liquefied acetylene gas in suitable, miscible proportions with a solvent, such as fusel-oil, and maintaining the same under'a reduced pressure, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
